Your post has a confusing Statement "when connecting positive ground after negative excessive sparks" The tractor came from the factory with 6v positive if gasoline, 12v if diesel. If you connected the battery backwards (negative ground) and sparks were made at the terminal, you probably welded the points in the cutout relay in the regulator together. This causes the generator to be connected to the battery when stopped. If you put a charger on the battery (now connected correctly) and the fan vibrated, that is what happened with a 90% probability. As John T indicates, disconnect the battery, and charge it while not connected. Tomorrow, or whenever, Disconnect the bat wire and arm/gen wires from the regulator. With an ohm meter, or a continuity tester, test between those two terminals on the regulator. if they are connected, the regulator should be considered fried. If they are open, no conduction, then (with the regulator disconnected) attach the charged battery. The Bat lead to the regulator will now be at battery volts. Touch it to the Bat terminal on the regulator. If no sparks, good. if sparks, the regulator is toast again. If no sparks, touch the Arm lead going to the generator to the Gen/Arm terminal on the regulator. If sparks, regulator is toast again. Replace it. Do as John T indicates to polarize the generator when a new regulator is attached. Jim

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
